Fft Search; Fft Search Setting - AOR AR-ALPHA Operating Manual

7. FFT Search

The AR-ALPHA has a FFT (Fast Fourier Transform) search function that enables high speed
searches using search bank data.
Unlike the ordinary search function that searches between a low frequency and a high frequency,
the AR-ALPHA FFT search examines a 10 MHz block of band data. When more than 10 MHz of
bandwidth needs to be searched, the AR-ALPHA will automatically continue the FFT search
process in 10 MHz increments.
